zen of the nited States; "Isidinfg' at. Poplar,

Bluff, Butler countflMissonri, have'invented I Addie -Machmes,ofiivhich the following is a fi1l1,c ear," andexact-deecri j art to which it appertains tomake and the same, reference being had to the accom draivings, forming part of this'specication,irnvhich-'-v Figure 1 is a vertical sectional view} ment'for a ding-machines. Fig. 2-is 'a-simh I This invention relates to a new and-useful" improvement in adding-machines, and =par-' ticularly to that class of adding+mach1nes in-' as a transversely-traveling stopper-rings, whose stops are set in position by the operation of the variouskeys.

Heretofore in this class of machines there are usually ten digit-keys, numbered from i to 9," inclusive;v and also containing the zerocharacter, which cooperate with one of a series of ten stops in a traveling carriage, there being as many series of stops (ten in each series) as required for the ca acity of the machine. In certain t es 0 this socalled cross-carriage mac inc there are order-keys, which upon being operated predetermine the position of the carriage .so that the first stop set up will be that of the highest order or denomination, the carriage then traveling as each digit-key is struck in a step-hy-step movement from left to In another type of cr0ss-carriage mac e there are no sc-called order-keys present to predetermine the position of the carri but the successive operations of the digitke in addition to setting up the stops also c act the movement of the carriage from right to left-as, for instance, in setting up the item $1500.00" the 1" digit-key is struck, then the 5 digit-key is struck, and then the 0 digit-key is depressed four times and causing the carnage to move six steps from right to left, placing the stop set up by I usn y loos tion, such as will enable others skilledin-t e v zero-keys.

When the keys have n'oper'ated,'as above described, to jan exem is in themechine, a handle at the right-hand side of themachinc is pulled forward to cause seg- ,-mej .l'tal racks to be moved until arrested by' f th'estops in the path of projections on said ,racksAWhich position. properly locates the printing-type inprinting line and also deter-- the extent of rotation of the totalizer- {,yvheelsinsccumulating the item in the totalmer.

of steps the carriage will be caused to move,

and more characters which will eventually be printed upon the operation of the handle by the depression of any of the supplementary The number of zero characters to be added to any given machine depends shine the capacity of the machine, there usua y being one less than the actual capacity of the machine.

the drawings I have shown a well-known t e of crors-carriege machine in which 1 is 0 base, and 2 the side frames extending up from the base, in which side frames are mounted the movable arts of the machine. 3 represents the so-cal ed numeral digitkeys, (shown in dotted lines in Fig. 4,) which numeral digit-keys terminate at their rear ends in longitudinally-Mined fingers orrangled under the stops in the cross-carriage 4. or sake of convenience these cross-carrings ste s are marked "0 "1 "2 "3" 4" "5 "6 "7 8, indicating that when one of said stops is elevated it will orrest the segmental rack in such position that the printing-typo corresponding to the posi- 'v trated {i drawings in printin of that or or will be actuated a corresponding tion of the stop in the series will be arranged line and also the totalizer-wheel distance. There is no stop for the 9 he because when the 9 key is depressed t e as mental rack moves forward the full limit. of

. ef stop-carriage is mounted on suitable ro lers runningon tracks and is connected to the cable fi of, a spri -drnm ,.7, which tends topull said carriage om right to !eft.

By referring to Fig. 4 it will be observed that part of the mechanism for actuating. the cross-carriage com rises a rack 10, mounted on the carriage, an a segmental gear 11 in mesh with said rack.

I 12jindicatesia series of keys which may be designated.- as zero ke s '7 to distirgsish them from the ordinary 't-keys of the Ir achine', and as shown in bear the characters 0, 0," 0 0," 11-05, (01],) I 07, and 08-1! these keys respectively are connected to the ends "of levers 13, pivotally mounted in a suitable frame extending u from the base, the rear ends of each of sai levers terminati115 inastop 14. 15 is a sliding member provi edwith a stop projection 16 at its rear end in lo 'tudinal ahnement with the stops 14.

The shdin memberand its projection 16 are" normally old in forward position by a spring 1-7. 0n the under side of the sliding member are ratchet-teeth for cooperatio with a pivoted pawl 18, carried by a sliding bar 19, mounted in suitable posts on the base. A spring 20 exerts pressure upon the bar 19 tending to move the same rearwardly at all times. The forward edge of the bar-19 is provided with a series of ratchet-teeth which co operate with aawl 21, pivoted in a post 22, extending up cm the base and having a spring 23 connected to its forward end, tend mg to hold' the rear end of the pawl in enagcment with the teeth of the bar 19. The orward end of pawl 21 carries a cross-bar 24, which is arranged across the stop-carrying levers13,:and also a lateral rejection 24", whioh'extends under the paw 18.

The operation of thc above-described parts is as follows: when the zero-key is depressed ig. 4, these key.

as shown in Fig. 2, one of the stops 14, in this instance the stop controlled by the zero-key 0, will be elevated and in so doing, by means of the lateral projection 24', raise the pawl 18 into en agcment with the forward tooth on the s idmg' member 15 and by means of the bar 24 depress the rear end of pawl 21 out of engagement with the rear teeth of the bar 19, permitting said bar to move rearwardly under the im elling action of its spring and carry with it the sliding member 15 until the projection 16 is arrested by the elevated stop 14. The depression of any of the key-shanks 12 o crates a bar arranged under the lower en s thereof carried by a bell-crank lever 25. This bell-crank lever is connected by a rod 26 to a lever 27, attached to a part of the esca ement mechanism, so that whenever one o the zero-keys is depressed and previous to the commencement of the movement of bar 19 rearwardly to a position determined by one of the stops 14 the escapement mechanism is disengaged, so as to permit travel of the cross-carriage independently of the control of said esca ement mechanism. This is accomplished by making the side members of the yoke 8 in sections, one of which, 8, upon which the escapement mechanism is mounted, is capable of slidin movement with respect to the hinged portion of the yoke-frame by means of a slot-andin connection, as shown in the drawings. The light s ring tends to assist the return of the movab c section of the yoke member carrying the escapement mec anism to norma position when the zero-key is eleased.

A continuation 26 of the rod 26 is connected to a bell-crank lever 28, whose other member is connected by a link 29 to the hub of a inion 30, slidable in a vertical direction on t e shaft 31. Meshing with this pinion and fixed on the shaft 11, on which the segmental gear 11 is mounted, is a segmental gear 32.

In the ordinary operation of the machine, whenever one o the numeral digit-keys is depressed, the segmental gears 11 and 32 are actuated, but the pinion 30, in its lowermost position, is rotated idlv. When, however, the pinion is raised by the depression of one of the zero-keys, it is thrown into mesh with rack-teeth 33 on the rear end of bar 19, so that the rearward movement of the bar will rotate the pinion 30, which is constantly in mesh with the segmental rack 32 irrespective of the position of the crosscarriage, and through t m segmental rack 11 move the cross-carriage along its track until the bar 10 is arrested. This movement of the cross-carriage causes a projection 34, carried bvonc of the movable arms of the yoke, to be placed under the zero-etc 1 bars in the crosscarriage, and com-implant when saul crosscarriage moves such zero-stop INIIH as rule F depifee oi o [the "i10 zero? nu't the-bar '19 t more reemfsrdlyee 1 ed yzt e pp o m s p-:
